What is called turbulence are precisely those states where the flow is irregular. However as this transition to turbulence depends on the constituents and parameters of the system and leads to very …
Why is turbulence dissipation $\\epsilon$ defined this way?
Oct 3, 2020 · This term is turbulence kinetic energy dissipation rate ϵ ϵ, which represents the rate at which Kolmogorov eddies energy is converted back into the flow’s internal energy. I understand the …
Estimating Aircraft Turbulence Severity from Velocity and Acceleration
Feb 21, 2025 · Define “turbulence”. When I’m on a plane and they say “we’re gonna go through some turbulence”, I usually think of high-amplitude oscillations in acceleration on me as what’s coming …
What does “eddy” mean in turbulence? - Physics Stack Exchange
Sep 26, 2022 · a newbie in turbulence study, very confused about the concept of eddy, I feel the word "eddy" having two meanings in fluid-mechanics maybe more and i'm not sure if i …
turbulence - Physical Explanation for "Kolmogorov -5/3 spectrum" in ...
According to Kolmogorov, the energy spectrum function of a turbulent fluid is given as, E(k) = Cϵ2 3k−5 3 E (k) = C ϵ 2 3 k 5 3 where ϵ ϵ is the energy flux and k = 2π r k = 2 π r where r r is the length scale. …
What causes wind gusts? - Physics Stack Exchange
Dec 26, 2022 · In this Wikipedia article, Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason turbulence is …
Is there any method to apply statistical mechanics to turbulence?
Dec 22, 2024 · Turbulence is not predictable in the sense that from one instant in time to the next a region of water will behave unpredictable. A von Karman vortex - flagpole vortex - for example is …
Transition from laminar to turbulent and vice versa
May 17, 2024 · The fluid is first flowing in a laminar manner. After some point x x I increase the velocity from u u to u′ u, the Reynolds number increases and when Re R e is higher than approximately 3000 …
Taylor's hypothesis in turbulence - Physics Stack Exchange
